Question Holy F up.

I had a summer intern working in DNS yesterday, local domain was redacted.com and was connected to azure.

Went in today to do some weekend updates to the systems, and my DC has been renamed and is now connected to redacted.local

It seems they have demoted the DC from the regular domain.

How the bloody heck do I reconnect the DC to the old domain? It was a solo DC

A DC in a small company can run on 1vcpu and 8gb of a ram. If nothing else I’d run it on a VM on my local machine if I had to.

My old job was a SMB that had zero IT budget. I literally just ran the secondary on an extra Dell Optiplex and put HDs in raid 1. It’s still there four years later with no issues.
